Claims

What is claimed is:

1. A wellbore assembly for use downhole in a wellbore, the wellbore assembly comprising:

a casing string comprising a mandrel, the mandrel including a side pocket in an inner region of the mandrel; and

a downhole device positioned within the side pocket of the mandrel, the downhole device including an electronics package, a power source, and a transmitter for transmitting data from the downhole device via a wireless communications link to a downhole tool for transmitting the data to a surface of the wellbore for monitoring a downhole environment of the wellbore.

2. The wellbore assembly of claim 1 , wherein the downhole device further includes an adaptor for coupling a downhole tool to the power source for recharging the power source via the downhole tool.

3. The wellbore assembly of claim 2, wherein the adaptor is a wet-stab connector.

4. The wellbore assembly of claim 1 , wherein the electronics package further includes a receiver for receiving data from a downhole tool or from another downhole device via the wireless communications link for receiving data from the surface of the wellbore for managing a performance of the downhole device.

5. The wellbore assembly of claim 1 , wherein the downhole device includes a region sized and shaped to couple to a downhole tool for positioning the downhole device within the side pocket of the mandrel while the casing string is downhole.

6. The wellbore assembly of claim 1 , wherein the power source includes a region sized and shaped for coupling to a downhole tool for removing the power source of the downhole device from the downhole device while the downhole device is positioned in the side pocket of the mandrel.

7. The wellbore assembly of claim 1 , further comprising a port within a wall of the mandrel for providing access to an annulus between the casing string and a wellbore for monitoring the downhole environment in the annulus.

8. The wellbore assembly of claim 1 , further comprising a downhole tool positioned within the wellbore, the downhole tool including a wireless receiver for receiving data from the downhole device via the wireless communications link.

9. The wellbore assembly of claim 1 , wherein the downhole device includes at least one of a sensor, a valve assembly, or an actuator.

10. The wellbore assembly of claim 1 , wherein the casing string comprises an additional mandrel having a side pocket; and

an additional downhole device positioned within the side pocket of the additional mandrel, the additional downhole device including an electronics package and a power source.

11 . The wellbore assembly of claim 10, wherein the additional downhole device is positioned at a distance to the downhole device for transmitting additional data via a wireless communications link to the downhole device for monitoring the downhole environment of the wellbore.

12. The wellbore assembly of claim 1 1 , wherein the additional downhole device is positioned at a distance to the surface of the wellbore for transmitting data to a device at the surface of the wellbore.

13. A method of monitoring a downhole environment of a wellbore comprising: collecting data regarding a downhole environment via a device positioned within a side pocket of a casing string, the side pocket in an inner region of the casing string;

transmitting data from the device to a downhole tool positioned downhole within the inner region of the casing string via a wireless communications link; and transmitting data from the downhole tool to a surface of the wellbore.

14. The method of claim 13, further comprising:

recharging a power source of the device via a downhole tool positioned within the inner region of the casing string while the device is positioned downhole in the side pocket of the casing string.

15. The method of claim 13, further comprising:

removing a power source of the device while the device is positioned downhole in the side pocket of the casing string; and

replacing the power source of the device while the device is positioned downhole in the side pocket of the casing string.

16. The method of claim 13, further comprising:

transmitting data from the downhole tool to the device for updating a performance of the device.

17. The method of claim 13, further comprising:

coupling a downhole tool to an adaptor of the device for recharging a power source of the device while the device is positioned downhole within the casing string.

18. The method of claim 13, further comprising:

collecting data regarding a downhole environment via an additional device positioned within an additional side pocket of the casing string; and

transmitting data from the additional device to the downhole tool positioned downhole within the inner region of the casing string via a wireless communications link.

19. The method of claim 18, further comprising:

transmitting data from the device to the additional device via a wireless communications link.

20. The method of claim 13, wherein the step of collecting data regarding a downhole environment via a device within a side pocket of a casing string further comprises:

collecting data regarding a downhole environment in an annulus between the casing string and the wellbore via a port in a wall of the casing string proximate the side pocket.
